The invention discloses bidirectional safety tongs for an elevator and an elevator device, and relates to the technical field of bidirectional safety tongs. The bidirectional safety tongs for the elevator comprise bidirectional safety tongs bodies, wherein pushing and fixing mechanisms are fixedly mounted on the inner surfaces of the bidirectional safety tongs bodies; telescopic combining mechanisms are movably mounted on the outer surfaces of both sides of the pushing and fixing mechanisms; a safety brake mechanism is fixedly connected with one end of each telescopic merging mechanism and comprises a fixing housing I; and a friction brake pad is fixedly connected with the inner wall surface of each fixing housing I. The outer surfaces of T-shaped blocks are pushed through extending and clamping columns; the extrusion in pushing heads is achieved through the cooperation with rebound lines; pushing heads are pushed through the elastic force of the rebound lines to one side; the friction force of the friction brake pads is increased by pushing the friction brake pads; the characteristic of pushing the friction brake pads is achieved; the problem that the friction force of the brake pads is reduced due to the insufficient pressure of the friction brake pads is solved; and the effect of increasing the friction force by pushing the friction brake pads is achieved.
本发明公开了一种电梯用双向安全钳及其电梯装置,涉及双向安全钳技术领域,包括双向安全钳,所述双向安全钳的内表面上固定安装有推动固定机构,所述推动固定机构的两侧外表面上活动安装有伸缩合并机构,所述伸缩合并机构的一端上固定连接有安全刹车机构,所述安全刹车机构包括固定外壳一,所述固定外壳一的内壁面上固定连接有摩擦刹片。本发明通过延伸卡接柱对T型块的外表面进行推动,配合反弹线在推动头的内部进行挤压,通过反弹线的弹力将推动头向一侧进行推动,对摩擦刹片进行推动增加摩擦刹片的摩擦力度,具备了对摩擦刹片进行推动的特点,解决了摩擦刹片压力不够降低了刹片的摩擦力度的问题,达到了对摩擦刹片件推动来增加摩擦力的效果。
